Devang Patel d12c0a2764 Ignore DBG_VALUE machine instructions while constructing instruction ranges based on location info. 
Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools.

Rafael Espindola 67c6ab8865 Change CodeGen to use .loc directives. This produces a lot more readable output 
and testing is easier.  A good example is the unknown-location.ll test that

every address change anymore.
